[0002] In order to promote the connectivity of river ecosystems upstream and downstream of hydropower projects and protect fish resources in rivers, modern hydropower projects often consider building new fish-passing facilities during construction. The main types of fish-passing facilities include fishways, fish lifts, and fish collection and transportation systems. In view of the characteristics of the high height and rapid water flow of ultra-high arch dams, traditional fish-passing facilities such as fishways and fish locks are difficult to meet the needs of fish passing the dam. The fish collection and transportation system adopts mechanized means, which can flexibly adjust the methods of luring, gathering and transporting fish, and can effectively solve the technical difficulties of fish passing the dam under the conditions of high dams and large reservoirs. Usually, a complete fish collection and transportation system includes the steps of luring fish, gathering fish, slipping fish, sorting, transporting fish and releasing fish. Among them, the sorting device is a key link in the system, which is mainly used to sort and classify the collected fish.

[0010] The fish inlet slide is T-shaped, and the fish inlet slide body is connected to the fish inlet slide baffle through a fish inlet slide hinge. When impacted by water flow, the fish inlet slide baffle opens and the fish swims into the sorting trough; when there is no water flow or the water flow impact is small, the fish inlet slide baffle is closed to prevent the fish from migrating out of the fish inlet of the sorting trough.

[0011] The bifurcation of the Y-shaped fish trough uses two fish partitions as gates of two bifurcated outlets. The outlet of the Y-shaped fish trough is connected to the temporary holding box. The two outlets are provided to classify carnivorous fish and non-carnivorous fish.

During this process, the fish inlet industrial camera identifies the number and species characteristics of the fish; Step 3: The fish slides into the sorting trough, and the right-angle motors at the fish inlet and outlet tighten the wire rope to lift the fish sieve to a shallow place. The fish species are identified again by human eyes. Then, a movable transparent partition is added to the sorting trough. The transparent partition is used to separate the fish to be measured close to the steel ruler. The steel ruler is used to achieve non-contact fish body length measurement. The weight of the fish can be estimated based on the body length and species data; Step 4: lift the fish screen to the position where it contacts the brush of the electric fish driving trolley, place two fish driving partitions between the electric fish driving trolley and the fish inlet, lift the fish driving partition close to the fish inlet to an appropriate height, use the movable partition to drive the carnivorous fish between the two fish driving partitions, lift the fish driving partition close to the electric fish driving trolley to exchange the positions of the two fish driving partitions, and repeat the fish driving partition operation steps until all carnivorous fish are classified; Step 5: Control the gate right angle motor to open the gate of the fish driving gate, drive the carnivorous fish to the other side of the electric fish driving trolley, and after the carnivorous fish have completed the position transfer, close the gate of the fish driving gate and move the two fish driving partitions out of the sorting slot; Step 6: Open the electric knife valve gate at the fish outlet, connect the Y-shaped fish trough with the temporary holding box, remove a fish trough partition, and control the electric fish driving trolley to move toward the fish outlet of the sorting trough.

The industrial camera at the fish outlet identifies the number and type of fish during this process. Step 9: After the second fish-driving action is completed, close the electric knife valve gates at the fish inlet and the fish outlet, use the drainage pipe to drain the water in the sorting trough, and lower the fish screen to the lowest point.

[0041] See attached Figure 6The electric fish-driving trolley 9 is composed of a box cover 901, a box body 903, a chassis 913, wheels 909, and a fish-driving fence 910. The box cover 901 is connected to the box body 903 by a hinge 912. The box body 903 is fixed on the chassis 913. A cable support plate 917 is welded on the outside of the box body 903. The wheel support block 905 is fixed to the chassis 913 by a wheel support block screw 914. The wheel support block 905 cooperates with the wheel shaft 904 through a bearing. Wheels 909 are arranged at both ends of the wheel shaft 904. The wheels 909 are arranged on the guide rail bracket 2.
